Featuring protean pianist Myra Melford, galvanizing bassist Mark Dresser and supremely musical drummer Matt Wilson, Trio M brings together three visionary jazz artists with extensive track records in adventurous ensembles. Documented on the acclaimed 2007 Cryptogramophone CD “Big Picture,” and the 2011 Enja/Yellowbird CD, “The Guest House,” this volatile ensemble explores compositions contributed by every member while maintaining a commitment to spontaneous improvisation. Unbound by piano trio conventions, the leaderless project erases distinctions between frontline and accompanist, requiring each player to shape the music’s flow as it unfolds. The resulting sounds can be fierce and beatific, playful and rigorous, earthy or abstract, extravagantly joyous or quietly introspective. The only constant is the triumvirate’s wondrous capacity to listen deeply and respond to one another other in unexpected ways, creating state of the art jazz that’s unbound by notions of genre, form, or conventional technique.
